This evneing, BBC One presents more celebrities donning fantastic outfits and learning iconic dance routines for Comic Relief, but this time the brave celebrities will be facing double the challenge - dancing and singing!

Let’s Dance For Comic Relief is back for Red Nose Day 2017, now bigger and better than ever before, as it's been supersized into Let’s Sing and Dance for Comic Relief.

The brand new series starts on Saturday 4 March at 6.45pm and will be hosted by Mel Giedroyc and Sue Perkins, marking their return to BBC One. The pair bring their own formidable and comic double-act to the show, with access-all-areas to the celebrities backstage.

In addition to the live studio performances, the show will hit the streets to enlist the help of the great British public in some of the biggest dance-offs ever. And with some surprise special guests in store, Saturday nights will be jam-packed of performances from some of the nation’s favourite faces.

The celebrity performers will face three live heats before a live grand final on Saturday 25 March. Together, the viewers at home and the judging panel will decide who makes it through to the final and the public vote to crown their winner, all in aid of Comic Relief.

In episode one, Mel and Sue are joined by TV Presenter and Radio 1 DJ Matt Edmondson, stargazer Russell Grant, funny girl Sara Pascoe, DJ’s Rickie and Melvin and Absolutely Fabulous actresses Helen Lederer and Harriet Thorpe. Comedy royalty Paul O’Grady, Jo Brand and Frank Skinner are on the judging panel, plus there will be some very special guests.
